We have one too and it's been one of our best investments since DD arrived on the scene!

I have super high standards when it comes to cleanliness and the presentation of our home and DH was getting sick of wasting our Saturday cleaning (not to mention seeing me so stressed trying to keep up with house work during the week) so DH organised her! She cleans DH's bosses house so she was highly recommended. We pay $30 an hour and she spends 3 hours a week at our place. She dusts, wipes, vacuums, mops, scrubs - the lists goes on! We are in a 4x2 so there is a fair bit of cleaning to do. She does a wonderful job and we are a much happier family because of her. If you can afford it then I say do it!
